Notes on use:

Hacked

2013-12-19: ID:251 (Oscilloscope #1) has been hacked to minimize the noise from the fan. A 47 ohm resistor has been placed in series with the fan (should be obvious if you open it). If it malfunctions or seems very hot please unhack it.

2014-04-21: ID:252 (Oscilloscope #2) has been hacked in a similar manner. Two of the nuts holding the power socket could not be replaced on reassembly, so it's missing missing two screws.
